Gender and quality of life in bladder cancer.

Abstract

464 Background: Quality of life among cancer survivors has been shown to vary by gender. Our objective was to evaluate differences in generic and bladder cancer-specific quality of life (QOL) based on gender among a large bladder cancer cohort. Methods: We performed a cross-sectional survey of bladder cancer patients using the Bladder Cancer Advocacy Network Patient Survey Network and Inspire platforms to determine generic and bladder cancer-specific QOL using the EORTC QLQ-C30 and Bladder Cancer Index. Patients were also queried regarding demographic, socioeconomic and clinical characteristics. The survey was advertised. We present descriptive statistics and a multiple linear regression model to identify factors independently associated with QOL domain score. Results: 972 respondents self-identified as patients with bladder cancer. Among respondents, 41% were female and 97% were white. The mean age was 67.6 years (range 29 to 93 years). Respondents were highly educated (67% completed college). 63% of patients identified as having non-invasive (NMIBC) cancer (n=578), 30% had MIBC (n=270), and 7% had metastatic bladder cancer (n=63). On multivariable analysis ( Table), female gender was significantly associated with worse generic QOL (p<0.001), bowel function (p=0.001), and sexual function (p=0.02), and women trended toward worse urinary function (p=0.06), controlling for age, race, stage, comorbidity and years since diagnosis. Conclusions: Lower generic and domain-specific QOL scores are more common among female bladder cancer patients. Differential impact by gender may be important for the development of tailored interventions to improve QOL for bladder cancer patients. [Table: see text]
